Extraction of Dicarboxylic Acids by ABC Extractants
Solvent Extraction and Ion Exchange, 2004Abstract Extraction of various dicarboxylic acids (maleic, malic, malonic, succinic, and tartaric) by acid–base couple (ABC) extractants was studied. The main extraction mechanisms were found to be ion‐pair and hydrogen‐bond formation. The relative contribution of each mechanism and extraction efficiency were found to be controlled by parameters such ...

Extraction of carboxylic acids with neutral extractants
Theoretical Foundations of Chemical Engineering, 2017In the review, the features of the interphase distribution of weak acids (K а < 10–2) in the systems containing neutral extractants have been considered. Experimental results of studies of the extraction of monocarboxylic acids have been described.

Extraction of acetic acid by binary extractants
Russian Journal of Inorganic Chemistry, 2013Interface distribution of acetic acid has been studied in systems with binary extractants, namely, trioctylmethylammonium di(2-ethylhexyl)phosphate, di(2-ethylhexyl)dithiophosphate, and dinonylnaphthalenesulfonate. It has been determined that, with the increase in the strength of the organic acid involved in a binary extractant, the extraction ability ...

On acidic organodiphosphorus extractants
Analytica Chimica Acta, 1971Abstract The distribution of di- n -butyl-ethane-(l,2)-diphosphonic acid (H 2 B 2 EDP) between 1 M (H, Na)ClO 4 and benzene or methyl isobutyl ketone has been studied radiometrically. The partition constants ofH 2 B 2 EDP are calculated. The results indicate that H 2 B 2 EDP remains monomeric in benzene up to a total concentration of 1.3·10 −2 M ,

Carboxylic acids as metal extractants
Talanta, 1974One of the problems in the extraction of trace elements is that matrix elements must usually be masked, involving the addition of large amounts of extra reagent and thus increasing the risk of contamination. If the maxtrix element is to be removed, an extraction system of high capacity is needed to avoid dilution effects. In this respect, long-chain or

Extraction of viral nucleic acids: Comparison of five automated nucleic acid extraction platforms
Journal of Clinical Virology, 2012Nucleic acid extraction has a major impact on the reliability of results in routine molecular diagnostics. Optimal isolation of nucleic acids and removal of inhibitors are essential.This study compares five different automated extraction platforms for the extraction of norovirus RNA from stool and cytomegalovirus (CMV) DNA from plasma samples.Norovirus
